Its low saturation and brightness provide a calm and serious visual impression.

The color #151405, also known as Green Waterloo, presents significant accessibility challenges. Its low luminance of 2.88 cd/m² falls far below the recommended contrast ratios for text and graphical elements as defined by WCAG. For example, to meet the minimum contrast ratio of 4.5:1 for normal text, the foreground text on a #151405 background needs to be significantly lighter. Similarly, to meet the enhanced contrast ratio of 7:1 for larger text and critical interface elements, even greater lightness is needed. Therefore, when using Green Waterloo, it is essential to pair it with very light colors to ensure readability and usability. Employing tools that check color contrast is crucial to guarantee compliance with accessibility standards and provide an inclusive user experience, particularly for users with visual impairments.
